"Since Trinny and Susannah brought dressing for your shape to the nation 13 years ago, we’ve based our wardrobes on a set of rules designed around what we believed our shapes to be," said Gaynor Davey, personal stylist manager at Debenhams Oxford Street.

“For many this has created confusion about anything outside those few shapes – and it has never been extended to men."

“We launched size 16 mannequins in our Oxford Street store at the end of last year and we’re continuing our commitment to promoting body confidence with more shapes and sizes for both men and women in our body-shape guide," added Gaynor.

The new Personal Stylist service can be found on the third floor of Debenhams on Oxford Street. The Personal shopper service is available in 115 stores, book appointments online at debenhams.com.
